Does anyone use Liqui Moly motor oil?

Money can buy anything, even a decal under the deckled of a vehicle with a certain brand name on it.

I doubt Euro manufacturers care one whit about AMERCIAN petro institute.

Mercedes, Porsche, BMW, VW-Audi ALL specify testing by independent labs to verify compliance with THEIR specifications, which go beyond generic EUROPEAN specifications.

Euro specs are ACEA, not API, and here's what Wikipedia says about ACEA

ACEA

The ACEA (Association des Constructeurs Européens d'Automobiles) performance/quality classifications A3/A5 tests used in Europe are arguably more stringent than the API and ILSAC standards. CEC (The Co-ordinating European Council) is the development body for fuel and lubricant testing in Europe and beyond, setting the standards via their European Industry groups; ACEA, ATIEL, ATC and CONCAWE.

Go ahead and put non DPF-safe motor oil in your diesel and see what you get. For a Mercedes that will have to be 229.51. 229.5 doesn't get it. The rule is don't even top up with noncompliant oil.

I have it in my 2001 at the moment - seems to run nice and smooth.
I emailed Liqui Moly and they recommended 'Liqui Moly 2332 Leichtlauf High Tech 5W-40 Engine Oil' as the best for my car, so I ordered a couple of 5 litre jugs through Amazon.
